Sounds like the Booster is leaking or the hose to the booster.
Start the engine a spray some WD40 or CRC around the booster and hose .If the engine speed changes it would indicate a vacum leak.
Boosters are usually bolted from inside the car and can be tricky to get to.
Hope this helps.

Brake jam in two wheels and brake paddle becom hard

It sounds like you have lost air pressure to your master cylinder via a tube from your engine. Or a Immobiliser has interferred with the operation of the braking.

96' Chevy K1500 Brakes are hard to press, but u hear a lot of air coming out, if i hold the brakes down for too long the truck cuts off.

It sounds like a problem with the brake booster, the air diaphragm that gives you power brakes. It is located right behind the brake master cylinder and mounted to the firewall.
Check the large vacuum hose to it for leaks. If the air is coming out of the unit itself, it will need replacing.
It will stop the engine because with a large air leak, the engine just sucks in way too much air. Hard brakes are also an indication that the booster is not working right. But check the hose first for leaking.
Good luck.

The brakes went to the floor and the light that has the brake with I P on top came on. I filled the master cyclindeer with brake fluid and pumped the brake back up ,but the brakes are soft agian. What can...

IF your brake pedal went to the floor, then you have a brake fluid leak somewhere. Even though you filled the reservoir with brake fluid, the system now has air in it. The first thing you need to do is find the leak and repair it. Most likely a wheel cylinder or caliper piston leaking. Once the repair is done, you will need to bleed the air from the rake system. Since you don't know anything about the brake system, I would strongly suggest having a professional mechanic do the work. If it is not done right, your brakes could fail.

When I push in on the brake padle it activate the brakes but when I lift my foot and try to brake again the paddle seems to harden untill theres no brakes.Brake-paddle remains hard for a couple of seconds...

There is either a restriction or break in the hose from the engine to the booster or booster is faulty.

You experiencing lack of brake boost assistance as you have correctly diagnosed.

Hose should have a one-way valve in it near the booster..

Theres a noise inside the van that sounds like an air leak down by the brake pedal and it has something to do with the brake system

Yes, the seal in the brake booster has gone bad, leaking vacuum, when it goes out the brake paddle will get very hard and hard to stop your van, the only fix is replacement of power brake booster, hope this was very helpful.

Having trouble with the brakes on my '90 Ford ranger. Replaced the master cylinder and still have very little braking power. Any help would be appreciated!

***Seek out professional help this vehicle is not safe to operate.***

Check the vacuum line going to the brake booster.

This is the big round chamber behind the master cylinder.

Hope this tip helps.
